She gave birth to their first daughter in January 2016, and by August, Kramer and Caussin separated while he attended an in-patient treatment center for sex addiction. It was not for another year before they reconciled and renewed their wedding vows. 

They discussed his struggle with infidelity on her podcast and remained honest with fans about his ongoing recovery efforts. On April 20, 2021, Kramer filed for divorce citing "inappropriate marital conduct" and "adultery."

At one point, Kramer estimated Caussin allegedly cheated on her with more than 13 women throughout their six-year marriage. The former couple remain amicable co-parents for their two children, Jace and Jolie.

"I just didn't believe it or think that I deserved it, so now that I know that I do – that's been the biggest shift," she said. 

"It makes me just want to go to all the girls and be like, 'You don't deserve what's happening to you right now. You deserve better!' 

"All the times that my friends tried to, like, just shake me down. Now I want to do that to all those other girls – ‘You deserve better.’ I see the other side of it now, and it's like, night and day."

Kramer added, "It all comes down to what you believe, because I did not believe that for a long time."
